Opcodes happen mostly for three reason.
1. Damaged game, broken CD/ISO etc. try making a image file preferably BIN/CUE format.
2. Savestates, save to a memory card, restart game load from memory, don't use save states so often.
3. Cheats, disable cheats.

That's all cya.

 

Sorry for needing more help, but how would I make an image file for the game?

 

Download and install imgburn.

Thou any burning software should be able to do this as well.
Start it, select "Create image file from disc" choose your CD/DVD drive and set where you want the file to be saved, just make sure that you select BIN under file type, so that you will have two files BIN and CUE, if you make a ISO it may not work properly.

 

OK, I've done that, and it works fine up until Sheila's Alps, where it crashes again with an opcode error. Any ideas?

 

It's copy protection, some games needs subchannels.

 

That's why i asked him ti make a proper BIN/CUE image, also that's not copy protection, if the copy protection would kick in Zoe would tell him, and then the game would troll him in may ways.

You could post a savefile i could check, but sadly there are no other reasons for opcodes the those that i mentioned, they're just game crashing errors, on a real PS1 the game would just freeze.

Here are the anti-piracy patches if you want to try that, but the game should work without them, i recently beat Spyro 3 with no issues.
Unpack them in your ePSXe folder patches, and check in ePSXe - Option - Auto Load PPF

I have a similar problem. I will save a state to my 3rd spot and it crashes and exits the game. When reloading and booting said save state, it crashes and exits the game. I tried restoring the second spot thinking something will be different. But it wasn't. I saved to a third spot and same thing. When I restored the first spot it restored and loaded. Then I stated saving to a different card and it crashed which saving. I was using bin/cue and iso and nothing changed so i believe its in pcsXr. funny thin is i had saved games from 1 2 and spyro 3 and everything was fine. then i made the mistake of overwriting the mem cards while unzipping a new version of the emu. i switched back to the old version but now everything is screwed up. can someone help me. i lost 63 percent in spyro 3 and about he same in spyro 1 now i have to start all over but with it crashing every second. i'm going to try another emu but this one i am using i got working with the right plugins and configuration. Someone Please help??..

i forgot to add the problem seem to be when it autosaved. i'd save in a third spot for going back to summer forest and it crashed out but the save i made while in sunny villa was the one that restored.
